775 > 785 (due to counterweights absent on 775) > 735 > 745 (wooden keys on 745 add more counterweight than the plastic 735 keys).

Apart from weighting differences, I believe the 785 & 775 actions are identical, and the 745 & 735 actions are identical.

The Boesendorfer binaural sound was a disappointment for me. If it would be on the same level like the CFX I would rank the 785 overall with 8.5 / 10.
The action is good but not perfect. I would rank the NV10 action as 9 / 10 and the action of a well regulated Steinway grand as 10 / 10.

Would it be much of an imposition to ask you to reconsider your score of 8.5?

Perhaps you’d be willing to increase it to a nice 9 out of ten? (No one really cares about the BallsandDorfer; it’s all about the CFX).

Surely, you can spare half a’ point; I mean, what’s a meager 1/2 point amongst friends?

Still, I don’t want to impose, and this is completely up to you, and I will accept whatever your final score is.

Hey, you know exactly that such ratings are not measurable values

There is also a cultural aspect. Ask a German to rate on a scale to 10 you rarely get the 10 as there is always something which can be improved.

I remember my company was evaluating customer satisfaction worldwide with the net promoter score. The management (some French/Spanish people) found the results in Germany were disappointing compared to other companies as satisfied customers had choosen 7 or 8

Some teachers propose some bonus question to help students get closer to 10.... then when can get a larger than 10 rating.

@ CentauriB

Can you measure the 785 weight at the very bottom of the key. If you run out of weights, you can add nickles they're about 5g each.

The minimum weight it takes to keep it all the way at the bottom.

Of all the 785 demos online this one is my fav. So not in the budget yet I keep torturing myself spending way too much time on reviews and videos.

The 745 is 72/73 grams at A0 and 50 grams at C8. So the upweight is about 15% higher than the downweight.

Beautiful performance and instrument! Pavel Janovsky: Prayer (Boccelli).

A new video from Richard Lawson Pianos about the 745 & 735:


A pretty standard sales spiel apart from this rather bold claim:

'With the CLP-745 however, you have wooden keys rather than the plastic keys you get with the CLP-735. So with the wooden keys, they are far more responsive and much more realistic feeling. That's because with the wood, the energy when you're playing is transferred the whole length of the key. So this gives you much more control, and much more power as well.'

Does anyone believe him?!
Nonsense? You be the judge!

I have compared CLP6xx with and without wood (NWX and GH3X keyboard), and found the wooden keyboard far more comfortable. I guess the keys are balanced differently (more inertia in the wooden keys)... but who care ? The difference of feeling is the most important thing.

Before the comparison, I was skeptical : does the wood fill only the marketing needs ?

I believe there are more people who prefer the NWX action to the GH3X so this basis suggests it isn't merely a marketing stunt.

I would pay more for NWX even just for the look and the feel when you sometimes touch the side of a key.

@Beowulf : you quote the half of the paragraph. I was skeptical before the comparison. Afterward, I get the answer : the wood get the keyboard more comfortable (it is not only marketing).

Wooden key action may be better in this case (and I believe you, it likely is) but it is not because of "That's because with the wood, the energy when you're playing is transferred the whole length of the key. So this gives you much more control, and much more power as well." - that's just complete and utter nonsense.

Osho

I guess this sentence (That's because with the wood, the energy when you're playing is transferred the whole length of the key.) is a clumsy wording for (that’s because with the wood, the key has more inertia).

Well, they could have more inertia (mass) by just using more plastic in the keys and making them not so hollow. (Of course there could some plastic injection molding limitations that I'm not familiar with.)

Or they could add counterweights like Kawai.

Of course "the energy when you're playing is transferred the whole length of the key" as long as the key doesn't flex no matter what it's made of.

+1

Which is a shame, as I don't think he was deliberately trying to deceive... He was just was so enamoured by the 745 that 'creativity' got the better of his thoughts!

@clothearednindcompo : I am sure they could achieve the same result differently... but they didn’t. You are right if you mean the presence of wood doesn’t matter, only the feeling does.


The energy can be transferred in two way : flex (like in a spring), or kinetic energy (we need speed and mass). I guess the wood add mass and increase the kinetic energy.
